Re: (Scott@USRT)

How much are your kits going for now, I am looking to cool my car down now that I'm running a stg 2 BBM S/C, I must say though the power gains on the S3 are AMAZING if they were made just using the boost cooler 63 hp is a lot of extra power, Thanks [IMG]http://*****************.com/smile/emthup.gif[/IMG]

Re: (JonVWluver)

Jon, the current pricing is available on the USRT website. Non-IC'd FI engines benefit tremendously from water/alcohol injection for two reasons.
a) Intake air temperatures are dropped massively and instantly which allows more fuel to be burned to produce more power/torque.
b) The tendency to detonate is reduced significantly which permits extra timing advance and MORE BOOST.
That customer's S3 was not modified between runs aside from spraying the WAI and cranking up the boost. Another example is a local customer's Corrado G60T which was detonating at 12psi boost. Now he's able to turn it up to 17psi before he starts to ping at all. Fwiw, he has yet to truly tune the system. So, even greater gains are likely in the near future.
I'll bet that WAI becomes a trend in VW engine tuning next year. We're lagging far behind a lot of the other marques in this regard! [IMG]http://*****************.com/smile/emthup.gif[/IMG]

Re: (Scott@USRT)

OMG, when I didn't think my world would get any worse, I finally see the group buy that at one point I wanted to start... now it's gone . ... sniff sniff ... But [IMG]http://*****************.com/smile/emthup.gif[/IMG] for bringing it out!
BTW, really dig the new website!

Re: (Scott@USRT)

Hi Scott right now i am in the process of building my car (seat Leon 1.8T) with a kit form Pagparts with a Gt2871r, 440cc, 3 inch maf, etc.
I have seen the benefits of wtare inj in a Jetta with a T3-t4 with no injection he could only bust 17 psi, with w-i he can boost it up to 22psi!!!!!
I just have two questions, one it wouldnt be dangerous to the rods the massive torque that you aquire with the w-i kit, and the second question do you ship out to México, if you do can you PM with the shippement cost and ill buy one of these on Monday.......
Thanks
Alex

Re: (ruso)

Here's some test data wringing out 3rd/4th gear uphill with my apr STG III gti.
WI made a huge difference in this cars performance. 16 C (28.8F) difference in peak air intake temps. Zero timing pull at 22 psi 93 octane with 93 in tank. I never tried 100 oct on 93 but a couple stg III guys have mentioned that it works with WI.

Alex, thanks for your support. Please let us know when you've got some nice results from your kit. Your connecting rods' long-term health depends on how hard you push. I can't tell you a specific power level where you'll start breaking parts. However, water/alky injection will help eliminate the sudden pressure spikes which bring sudden death to engine internals.

Re: (ruso)

Sure, the water pump is 8" long, approximate 4" tall (including rubber mount pieces), and 4" wide at the mounting bracket. The tank measures 6.5" x 4" x 5". That kind of volume lasts about a week in my friends 500whp Mustang. He's got no space under his hood, so he stuck both his pump and tank in the trunk. They're stashed behind his interior trim panels with Dynamat applied to muffle sound. It's a really slick set up. The kit in my Scirocco is installed on the floor behind the passenger's seat. However, most folks just keep everything under the hood.

Ok, so does the pump carry similar noise characteristics as an in-line fuel pump?

Mmm... nah, it isn't as high-pitched and whiny as that. Rather, it's more of a strong hum. When mounted on the rubber standoffs it's not annoying at all. The reason why my Mustang buddy used the Dynamat is because he put the pump inside the car. Fwiw, I used no sound deadening at all and it doesn't annoy me. Then again, I can't hear a damned thing over the ITBs or my electric power steering pump (mounted on the floor beside the Snow pump).

I have another company's system that uses the same pump , made a bracket and mounted it to the OEM SMIC brackets , very stealth and you dont hear anything out there . Just a few install tips . If you mount the pump with the motor side facing up, make sure you silicone around ANY and ALL opening ( where the wires go in, around outerside of the base plate and espec the weep hole ) other wise road water will find its way in the motor and short it out ( ask me how i know ) Another thing i found that helps improve the performance is i removed and blocked off / bye passed the pressure switch in the pump , you get ALOT better spray . I havnt had a chance to use it on my stage 3+ with 100 octane program ,with 93 in the tank . But i used it with good results when it was a APR ko3 100 oct program and 93 in the tank , very little timing pull and great performance [IMG]http://*****************.com/smile/emthup.gif[/IMG] IMO water / meth systems work well Bob.G

Re: (ruso)

Great kit, i'll def. have to pick one of these up this spring, once i rebuild my new ride/finally decide between a turbo kit.
The other option i was looking at, tho, was propane injection? I used to be interested in 3000gt's before i decided they were maintainence nightmares, and they were all about propane injection for detonation control.
Any idea how the water/alcohol injection compares to propane, pros and cons? Thanks! [IMG]http://*****************.com/smile/emthup.gif[/IMG]

Re: (nathankaufman)

Propane injection is best used to make extra power on a diesel engine -not gasoline. The addition of propane (usually pre-turbo) to any diesel engine, whether turbocharged or normally-aspirated, introduces more fuel to engine, without additional airflow. This is a big deal for a diesel and this mod can produce nice benefits if done correctly. The problem is that there simply aren't very good propane injection kits on the market. What I've seen are all fairly crude.
Now, water/alcohol injection (WAI) is a different beast entirely. Rather than primarily serving as supplementary fueling, the issue here is detonation control. With this method, octane is increased radically. So, boost or nitrous can be cranked up without detonation. WAI can be used very effectively on both gasoline and diesel engines. And, WAI can be used with propane injection on a diesel for really impressive power/torque improvements.

Re: (TSTARKZ123)

Our new shop is located in South Jersey -near Philadelphia, PA. That place is still under construction, though, so we may need to do the work at another facility close by. If you're interested in getting some work done, please shoot me an IM or email. [IMG]http://*****************.com/smile/emthup.gif[/IMG]

Re: (JettaRed)

Bill, the group buy is actually over. However, we've got the kits generally available. You're an influential figure around here as far as water injection is concerned. I'd be pleased to "hook you up" as the young folks say.

is this an appropriate setup for a daily driver? does it require tweaking/calibration etc. I think it looks like a good kit for a serious setup, but i'm not sure it fits what i'm shootin for.
Example: jump in car, turn key, and we're off. let sit for anywhere between 3 hours and 10 days and repeat.
Also, would a snobby rich chick complain about the noise of the pump on a late-nite cruise through some quite back roads?
